沙(sha)(sha)拉(la)(la)一般是幾種原(yuan)料混合生(sheng)(sheng)制(zhi)(zhi)或(huo)腌制(zhi)(zhi)，如果(guo)蔬菜(cai)、水(shui)果(guo)上(shang)粘附(fu)的細(xi)菌、寄(ji)生(sheng)(sheng)蟲沖洗(xi)不徹底(di)，則直接造(zao)成(cheng)成(cheng)品的污染(ran)(ran)；其次(ci)，制(zhi)(zhi)作(zuo)時(shi)加(jia)工(gong)(gong)環(huan)境衛(wei)生(sheng)(sheng)不良、加(jia)工(gong)(gong)容(rong)器(qi)生(sheng)(sheng)熟(shu)不分、加(jia)工(gong)(gong)人員(yuan)自身帶(dai)菌、加(jia)工(gong)(gong)人員(yuan)衛(wei)生(sheng)(sheng)意識不強等(deng)也可造(zao)成(cheng)細(xi)菌的二次(ci)污染(ran)(ran)。因此，提醒(xing)消(xiao)費者制(zhi)(zhi)作(zuo)沙(sha)(sha)拉(la)(la)時(shi)除應保證原(yuan)料質(zhi)量(liang)外，制(zhi)(zhi)作(zuo)時(shi)要(yao)徹底(di)清(qing)洗(xi)蔬菜(cai)、水(shui)果(guo)等(deng)原(yuan)料，容(rong)器(qi)和工(gong)(gong)具徹底(di)清(qing)潔消(xiao)毒，避免原(yuan)料、工(gong)(gong)具、人員(yuan)之(zhi)間的交(jiao)叉污染(ran)(ran)，保障沙(sha)(sha)拉(la)(la)的衛(wei)生(sheng)(sheng)質(zhi)量(liang)，避免食用沙(sha)(sha)拉(la)(la)引起的食物中毒。

　　競道細菌檢(jian)測儀為全新升級產品(pin)，大屏幕觸摸顯示屏，代替(ti)傳統按鍵(jian)。操作(zuo)采用生(sheng)(sheng)(sheng)物(wu)化(hua)學反應(ying)方法檢(jian)測ATP含(han)(han)量(liang)(liang)(liang)(liang)，ATP熒光(guang)(guang)檢(jian)測儀基(ji)于(yu)螢火蟲發光(guang)(guang)原理，利用“熒光(guang)(guang)素(su)酶—熒光(guang)(guang)素(su)體(ti)系(xi)”快(kuai)速檢(jian)測三磷酸腺苷（ATP）。ATP拭(shi)子含(han)(han)有可以(yi)(yi)裂解(jie)細胞(bao)膜的(de)試劑(ji)(ji)，能(neng)將細胞(bao)內ATP釋(shi)放出(chu)來，與(yu)試劑(ji)(ji)中含(han)(han)有的(de)特(te)異性酶發生(sheng)(sheng)(sheng)反應(ying)，產生(sheng)(sheng)(sheng)光(guang)(guang)，再用熒光(guang)(guang)照(zhao)度計檢(jian)測發光(guang)(guang)值，微生(sheng)(sheng)(sheng)物(wu)的(de)數(shu)量(liang)(liang)(liang)(liang)與(yu)發光(guang)(guang)值成正比，由于(yu)所有生(sheng)(sheng)(sheng)物(wu)活細胞(bao)中含(han)(han)有恒(heng)量(liang)(liang)(liang)(liang)的(de)ATP，所以(yi)(yi)ATP含(han)(han)量(liang)(liang)(liang)(liang)可以(yi)(yi)清晰地表(biao)明(ming)樣品(pin)中微生(sheng)(sheng)(sheng)物(wu)與(yu)其(qi)他生(sheng)(sheng)(sheng)物(wu)殘余的(de)多(duo)少，用于(yu)判斷衛(wei)生(sheng)(sheng)(sheng)狀況(kuang)。
